Miniaturized Broadband Lumped-element In-phase Power Dividers

摘要

This paper describes miniaturized broadband lumped-element in-phase power dividers. We first propose two types of miniaturized broadband lumped-element in-phase power dividers composed of two inductors, a resistor, and two capacitors. Next, we use a simulation to compare these dividers with conventional power dividers. The simulation results reveal that the proposed lumped-element in-phase power dividers can help miniaturize circuits (by decreasing inductances by about 30, reducing the number of necessary capacitors by half, and decreasing necessary capacitances by about 30 as compared to conventional lumped-element dividers) and attain broadband frequency characteristics (by increasing normalized operating frequency bandwidths (f/f_0) by about 80 as compared to conventional lumped-element dividers).
